Acertain string can withstand a maximum tension of 39. n without breaking. a child ties a 0.43 kg stone to one end and, holding the other end, whirls the stone in a vertical circle of radius 0.98 m, slowly increasing the speed until the string breaks. where is the stone on its path when the string breaks (top of the circle, middle of the circle or bottom of the circle)

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
